    (54) Differential amplifier with current steering to enhance slew rate


    (57) A steering circuit (10) in a differential amplifier having a pair of differentially arranged input amplifiers (A1 and A2) steers current from a pair of current sources (11 and 12) in such a way as to enhance slew rate without increasing offset voltage. The steering circuit is formed with a pair of steering amplifiers (A3 and A4) arranged in a differential configuration through a pair of resistors (R3 and R4).
